They kind of glossed over the real value, which is using it as a template to automate a step at a time:
"Each step of the procedure is now encapsulated in a function, which makes it possible to replace the text in any given step with code that performs the action automatically."
It breaks the work down into more manageable tasks. I probably wouldn't give it to users until it was done, but putting placeholder functions is a common strategy.
I think it would come down to if the fold in the wrapper was facing up or down. If the tire had tread, I don't think it would matter, but if the slit were facing down, I think the wax paper would keep it from sticking. Unless the pressure squeezed the butter out, in which case I think you'd end up with most of the button on the tire and the wrapper on the ground.
